SPECIFICATION forming part of Itetters Patent No. 506,473, dated October '10, 1893. i Application tiled January 24, 1893. Serial No. 459,559. (No model.) Y

To a/YZZ whom. it may concern.-

`Be it known that l, 'GILBERT H. CoNKLINa citizen ofthe United States, and a residentv and forth during the operation of the engine,

to alternately bring the ports in its ends into alignment with similar or corresponding ports in the stationary bed upon which the `cylinder reciprocates, thus acting in a reverse manner to the ordinary stationary cylinder engines provided with slide-valves.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a plan view of an engine constructed in accordance with my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a central longitudinal sectional view of one end of the engine. Fig. 4 is a cross section on line ct-a, Figs. 2 and 3. Fig. 5 is a horizontal section on the line b-b, Figs. 2 and 3. Fig. 6 is a cross section on the line c-c, Figs. 2 and 3. Fig. 7 is a detail elevation of the exhaustpipe and handle for reversing the exhaustvalve. Fig. 8 is a top view of the bed upon which the cylinder reciprocates. Fig. 9 is a detail view of the inner end of the governor. Fig. 10 shows detail views of the devices for holding the cylinder on the bed. Fig. 11 shows the means for actuating the cut-off lever. y

In the said drawings, the reference numeral 1 designates the base of the engine, and 2 the uprights which support the driving shaft.

The numeral 3 denotes a horizontal bar or plate provided with a standard 4, secured to the base 1. Firmly secured to this plate 4 is the bed 5, concaved upon its upper side to correspond with the contour of the cylinder provided with a series of horizontal steam passages 7 and 8, and lateral steam passages 9, 10, and 9, 10a. These passages 9 10 and 9, 10a are adapted to register and communicate with the ports 12, 13, and 14, 15, in the bed 5,.as hereinafter described',which in turn communicate with the cylinder through ports 6a and 6b. At one end the passages 7 and 8, communicate with diagonal passages 16 and 17, in a standard or upright 4, which passages lead to and communicate with a steam passage 19, in said standard adapted to be supplied with steam from any suitable source.

At the upper ends of passages 16 and 17, are Valves 20 and 21 consisting of screw-rods provided with hand-wheels 22, by which they may be rotated to open and close communition between passages 7, 16, and 8, 17.

At its inner end the bed 5 is provided with a downward. extension 23, provided with exhaust passages 24 and 25, which communicate at their upper ends with passages 7 and 8, while at their lower ends they communicate with an exhaust pipe 26. Located in the exhaust pipe at its upper end is a two-way exhaust valve 27, provided with an operating handle 28, so that said Valve can be rotated so as to communicate with either passage 24 or 25. Near the upper end of passage 19,` the-standard 18 is provided with a sleeve 29, in which is located a Valve 30, consisting of a rod provided with a hand-wheel 31. This rod is aligned with a plug 32, against which its end is adapted to abut when pushed in. Connected with this screw-rod is one end of a lever 34 pivoted to a lug 35 formed on the eX- tension y23. The opposite end of this lever is provided with a stud 36 which works in a groove 37 in the ange of a sleeve 38, which embraces and works upon the driving shaft 39, journaled in the uprights 2. This sleeve is provided also with a ange 40 to which is pivoted a series of arms 41 havingballs or weights 42 at their free en ds.

To the arms 4l intermediate of their ends are pivoted arms 42, which in turn are pivoted to a sleeve 43 on shaft 39. Secured to this shaft 39, is a collar 43a, against which abuts one end of a coiled spring 49, the other end of` which bears against the sleeve 38.

6, which is supported thereby. This bed is y IOO Secured to the driving shaft are eccentrics 46, vupon which work straps 47,formed-With or secured to the rods 48, pivoted to studs 49 on opposite sides of the cylinder.

The numeral 50 denotes the piston, 5l the piston-rod, 52 the pitman, and 53 the crank..

The steam cylinder` is provided on itsv under" 'side with a downwardly projecting rod 54,

Vand valvell is closed,vr steam Lis admitted throughrasupply pipe to passage'lf), andfrom Ythencez-p'asses through passages 16,f7,fand lO,

When the engine runs too slow however, the operation .-is,reversed,an'd the steam supply increased.
